Normal force is mass x gravity, so mass x 9.81
Answer:
(a) 0.3778 eV
(b) Ratio = 0.0278
Explanation:
The Bohr's formula for the calculation of the energy of the electron in nth orbit is:

(a) The energy of the electron in n= 6 excited state is:


Ionisation energy is the amount of this energy required to remove the electron. Thus, |E| = 0.3778 eV
(b) For first orbit energy is:




Ratio = 0.0278
Answer:
(a) gravitational potential energy converted to kinetic energy
(b) chemical energy is converted to light or heat energy
(c) mechanical energy is converted into kinetic energy
Carbon atoms can form straight, and branched chains, and rings
